上传视频到优酷服务器时出错，求高手指点迷津~
在优酷的上传视频API中（WINFORM），要执行一系列的操作，前面已陆续测试成功，现在在一个叫“upload_slice”的API中需要传递二进制数据，他的API具体说明如下：upload_slice
InterfacePOST http://gX.upload.youku.com/gupload/upload_slice?< .. parameters .. >
< .. BINARY DATA .. >
Parameters
upload_token: string, MUST provide.
slice_task_id: int, MUST provide. the slice upload task ID.
offset: int64, MUST provide. the offset in the source file.
length: int, MUST provide. the data length.
crc: string, CRC32 of the data slice in hex string. default is empty string (””).
hash: string, MD5 of the data slice in hex string. default is empty string (””).
data: binary.
Note: One of CRC or HASH is recommented for error testing and slice re-uploading.
Return Value
error: object. Only returned when error occured.
code: int.
type: string.
description: string.
slice_task_id: int, MUST provide. the next slice upload task ID.
offset: int64, MUST provide. the offset of the next slice in the source file to upload.
length: int, MUST provide. the data length of the next slice to upload.
transferred: int64. the data length that already uploaded.
finished: boolen, whether or not the file is totally uploaded.
Error Codes
120010205 - Invalid upload session id
120010212 - Internal error: memory error
120010218 - CRC check error
120010219 - Resource unavailable
120010221 - Duplicated operation
120010224 - Bad request
120010225 - Hash check error
See Error Definition for full list of error definitions.
Sample (for demo only; layout for ease of reading)
POST /gupload/upload_slice?upload_token=1a2b3c4d
&slice_task_id=1328792850123
&offset=12345678
&length=12345
&crc=dfc6f27b
Host: g01.upload.youku.com
< .. BINARY DATA .. >

"offset": 12358023,
"length": 12345,
"transferred": 12358023,
"finished": false }
现在的问题是，如果把包含“文本”和二进制数据的内容一起POST到服务器？
难道是把2部分分开再合并起来发送？如我下面的代码所示：
/// <summary>
/// 合并数组
/// </summary>
/// <param name="first"></param>
/// <param name="second"></param>
/// <returns></returns>
private byte[] mergerArray(byte[] first, byte[] second)
{
byte[] result = new byte[first.Length + second.Length];
first.CopyTo(result, 0);
second.CopyTo(result, first.Length);
return result;
}
private void btn_upload_slice_Click(object sender, EventArgs e)
{
//upload_slice
byte[] data2 = File.ReadAllBytes(file_name);
Encoding encoding = Encoding.UTF8;
uint crc = my_CRC32.CalculateDigest(data2, (uint)0,length);
//MessageBox.Show(crc.ToString());
string postData = "upload_token=" + upload_token + "\r\n";
postData += ("&slice_task_id=" + slice_task_id + "\r\n");
postData += ("&offset=" + offset + "\r\n");
postData += ("&length=" + length + "\r\n");
postData += ("&crc=" + crc + "\r\n");
//postData += ("&data=" + "\r\n");
//MessageBox.Show(postData);
//postData += File.ReadAllBytes(file_name)+ "\r\n";
byte[] data = encoding.GetBytes(postData);
string content = ZdSoft.Framework.Helper.HttpRequest.DoPostRequest("http://g" +
gX + ".up.youku.com/gupload/upload_slice",
mergerArray(data, data2), 1);
//MessageBox.Show(content);
btn_upload_slice.Enabled = false;
}
其中，ZdSoft.Framework.Helper.HttpRequest.DoPostRequest是我自己的类，发送POST请求的，mergerArray是合并数组数据用的，但是服务器一直返回400，我要怎么解决？求高手指点！ upload 优酷 视频上传 二进制 post --------------------编程问答-------------------- 是把参数弄成地址,再把二进制post过去!
